vs vision shell

1
Hi, currently my lab is using vision shell to run experiments but we are
looking for something that is easy to use on the PC and are in the process
of researching other programs. So I had a couple of questions about the
capabilities of psychtoolbox:

Can you create graphics in the program? Is there a color table?

Is is difficult to draw complex shapes?

Is there a speech capability in the program?

What language is it programmable in? C?

Is the motion smooth in moving graphics or animation?

Is there any way to change the parameters of a program before each
experiment without having to program the changes in?

Is the counting / timing function independent of the clock or does it
directly access the clock?

Does psych toolbox devote the operating system solely to the application
when running?


Any help would be really appreciated. Thanks a lot.

dear alex

you should take a look at the website. several parts are devoted
to introducing new users, and provide answers to most of your
questions.
http://psychtoolbox.org/

Briefly. it's easy to create complex graphics. there is full control of
the CLUT. it's programmed in MATLAB. there is speech in the
Mac version; i don't know what Win:MATLAB offers by way of
speech. Everything is frame-accurate; animations are perfect. (At
least on Mac; Win testing has been more limited.) You'll control
everything from your program; use any style you like.
